histedit: move topmost bookmark movement to a separate function

histedit treats topmost bookmark movement specially. The rest of the
bookmark movement could be handled by scmutil.cleanupnodes. So let's move
the special logic out to make the patch easier to review.

Tests if hgweb can run without touching sys.stdin, as is required
by the WSGI standard and strictly implemented by mod_wsgi.
